Zusammenfassung:	Abstract: "Although the depth of an object if perceived quasi-quantitatively from a single two-dimensional line drawing, previously published interpretation methods of a line drawing do not wholly explain this phenomenon. For example, labeling methods interpret a line drawing only qualitatively, model-based methods are applicable only for predetermined objects, and regularity-based methods are valid only for regularly-shaped objects. An inclusive cognitive model for depth perception from a single line drawing is proposed. Unlike most other approaches, it can explain the quasi-quantitative interpretation of irregularly-shaped and unfamiliar objects. It interprets a drawing as the one of many geometrically possible objects which is most likely to produce the drawing The likelihood of producing the drawing depends on both the likelihood of an object (object likelihood) and the likelihood of a view of the object (view likelihood). The new concept, view likelihood, enables the interpretation of irregularly-shaped objects. The likelihood of the projected area is proposed as an approximation to view likelihood, and it enables the interpretation of unfamiliar objects. This paper also examines line drawings which are drawn to communicate three-dimensional shapes. In this situation, the probability that an interpretation based on the view likelihood is correct increases.
